Been reading my way through the archives of Yvain's blog, a lot of good stuff beyond the topics on Lesswrong.

Anyone who's a fan of Star Trek, Firefly, etc, and likes (or doesn't mind) challenging games should play indie PC game FTL. It's a really fun and well-designed pseudo-Roguelike about managing a small spaceship as it races through space fighting and exploring, and is only $10 on Steam or from http://www.ftlgame.com/ . I've seen several people describe FTL as "the game I didn't know I always wanted", and I felt the same.

It's also good practice for risk and crisis management - there's a lot of literal putting out of fires :).

The Rules of the Game Called Psychological Science.

This article about envy free cake division/introductory mathematical dispute resolution is pretty cool. For that matter h2g2, as a whole is worth checking out, abliet less relevant to LW. What To Do in the Face of Certain and Imminent Death is particularly good.

Rationality and Charity:

Quine and others have recommended principles of charity which discourage judgments of irrationality. Such principles have been proposed to govern translation, psychology, and economics. After comparing principles of charity of different degrees of severity, we argue that the stronger principles are likely to block understanding of human behavior and impede progress toward improving it. We support a moderate principle of charity which leaves room for empirically justified judgments of irrationality.

Found while looking for literature on optimal philanthropy. :)
